DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light bulb socket used for mounting a light bulb on a vehicular lamp, and more particularly to a light bulb socket suitable for a lamp using an incandescent lamp as a light source, such as a rear combination lamp and a side marker lamp. It is related to.

[0002]

2. Description of the Related Art FIGS. 3, 4 and 5 show examples of such a conventional light bulb socket. First, a socket body 91 of a light bulb socket 90 shown in FIG.
And the connector housing 93 are formed on a straight line,
In the socket body 91, a positive electrode terminal having a center electrode portion formed on the socket 92 side and a connector terminal portion 94 formed on the connector housing 93 side, and a peripheral electrode portion and a connector terminal portion are similarly formed. The negative electrode terminal 95 is mounted.

In this case, the socket body 91 is
Since the connector 2 and the connector housing 93 are on a straight line, the respective terminals 94 and 95 can be inserted and fixed in, for example, the socket 92 direction. Is at a predetermined position, and it is relatively easy to set the connector terminal portion also at the predetermined position on the connector housing 93 side.

Accordingly, both when the electric bulb 10 is inserted into the socket 92 and when the vehicle body-side coupler 20 is inserted into the connector housing 93, that is, the socket 92 and the connector housing 93 are formed independently. Thus, the socket 92 and the connector housing 93 do not require wiring as compared with the case where the socket 92 and the connector housing 93 are formed independently, and can be simplified.

On the other hand, in the case of the above configuration,
Since the distance D1 from the mounting surface 91a of the socket body 91 to the vehicle lighting device (not shown) to the rear end of the vehicle body-side coupler 20 is long, and a wide gap is required between the vehicle body and the vehicle lighting device. Is a rear combination lamp, which causes problems such as a reduction in trunk capacity. For this reason, the distance D1 has been required to be as short as possible.

FIG. 4 is a diagram developed in response to the above demand.
The central axis Y of the connector housing 83 of the socket main body 81 is provided so as to be orthogonal to the central axis X of the socket 82, that is, in an L-shape. The distance D2 from the mounting surface 81a to the rear end is shortened assuming that the socket 82 is inserted from a direction orthogonal to the central axis X of the socket 82.

[0007]

However, in the above-described light bulb socket 80 shown in FIG. 4, only the connector housing 83 is simply orthogonalized as shown, and the positive terminal 94 and the negative terminal 95 are mounted. In order to enable the above, those having substantially the same shape as that shown in FIG. 3 are used. Therefore, the vehicle body side coupler 30 is connected to both terminals 9.
A very special structure for connecting the side plates 4 and 95 from the side is required, which causes a problem of cost increase.

[0008] FIG.
In addition to the connector housing 73 of the socket body 71, there is also a light bulb socket 70 in which the connector terminal portion 74a (75a) of the positive electrode terminal 74 (negative electrode terminal 75) is orthogonal to the socket 72. Since the terminal 74 and the negative terminal 75 cannot be mounted in a later process, insert molding must be performed at the time of molding the socket main body 71, which complicates the production process and further increases the cost. The solution of these points has been an issue.

[0009]

According to the present invention, as a specific means for solving the above-mentioned conventional problems, a socket for holding a base of a bulb and a connector housing are integrated, and the socket and the connector housing are integrated. And L
In the L-shaped lamp socket arranged in a mold, both the center electrode and the peripheral electrode of the socket are integrated into a substantially L-shaped connector terminal to form positive and negative L terminals, and a back surface of the L-shaped lamp socket. The L side is provided with an insertion opening corresponding to the shape of each of the L terminals, and the positive and negative L terminals are inserted and fixed from the back side.
The problem is solved by providing a mold lamp socket.

[0010]

Next, the present invention will be described in detail based on an embodiment shown in the drawings. 1 and 2 is an L-shaped lamp socket according to the present invention. The socket body 2 of the L-shaped lamp socket 1 is formed by integrating a socket 3 and a connector housing 4 with each other.

And a negative electrode L terminal 6 in which a peripheral electrode portion 6a and a connector terminal portion 6b are integrally formed, and is mounted on the socket body 2. At this time, the center electrode of the positive electrode L terminal 5 is formed. The portion 5a is along the central axis X of the socket 3, and the connector terminal portion 5b is along the central axis Y of the connector housing 4.

Similarly, in the negative electrode L terminal 6, the peripheral electrode portion 6a extends along the central axis X of the socket 3, and the connector terminal portion 6b extends along the central axis Y of the connector housing 4. Accordingly, both the L terminals 5 and 6 of the positive and negative electrodes are formed as substantially L-shaped ones similarly to the socket body 2.

On the other hand, the socket body 2 has a socket 3
Insertion openings 4a, 4b opening on the side that is the back side with respect to the insertion direction of the

First, for example, a spring-shaped center An electrode portion 5a is provided. At this time, the center electrode portion 5a has a conventional regular positional relationship with the socket 3, that is, along the center axis X of the socket 3.

A connector terminal portion 5b is formed on the positive electrode L terminal 5 on the side of the connector housing 4. At this time, the connector terminal portion 5b also has a regular positional relationship with the connector housing 4 in the conventional manner. That is, the central electrode portion 5a extends along the central axis Y of the connector housing 4 as described above.
And the connector terminal portion 5b are orthogonal to each other and have a substantially L-shaped shape.

At this time, if the L-shaped lamp socket 1 is used for a vehicle lamp, the connector housing 4 and the connector terminal portion 5b are
If a standard shape used when connecting the wiring of this kind of vehicle lamp and the vehicle body side is used, the vehicle body side coupler 2
There is no need to change the design for 0, etc., which is convenient.

In addition, between the center electrode portion 5a and the connector terminal portion 5b of the positive electrode L terminal 5, an engaging portion 5c for engaging with the socket body 2 is formed, for example, in a substantially U-shape. The engaging portion 5c is provided with an engaging claw 5d. When the positive electrode L terminal 5 is inserted into the socket body 2 from the insertion opening 4a, as shown in FIG. The socket 2 is elastically engaged with and fixed to a step 2a provided in the socket body 2. In the insertion direction, the depth of the insertion port 4a is appropriately set, and the positive and negative L terminals 5, 6 are abutted at appropriate portions to regulate.

The above configuration is basically the same for the negative electrode L terminal 6, and the negative electrode L terminal 6 has an engaging claw 6d provided between the peripheral electrode portion 6a and the connector terminal portion 6b. A portion 6c is provided, and engagement with the socket body 2 is performed by the engagement claw 6d. At this time, the connector terminal portion 6b is connected to the connector terminal portion 5b of the positive electrode L terminal 5.

Alternatively, the positive and negative L terminals 5, 6 formed in a substantially L-shape by the peripheral electrode portion 6a and the connector terminal portions 5b, 6b are inserted through insertion ports 4a, 4b provided on the back side of the socket body 2. By fixing the connector housing 4 to the socket 3
In addition, assuming that the electrodes and terminals are present at the proper positions, it is possible to use the vehicle-body-side coupler 20 as in the past, and at the same time, to perform complicated manufacturing such as insert molding when forming this type of L-shaped lamp socket 1. This eliminates the need for a process.

[0020]

As described above, according to the present invention, both the center electrode portion and the peripheral electrode portion of the socket are integrally formed with the connector terminal portions in a substantially L-shape to form positive and negative L terminals. On the back side of the L-type lamp socket, an insertion opening is provided in accordance with the shape of each of the L-terminals, and the L-terminals of the positive and negative electrodes are inserted and fixed from the rear side to form an L-type lamp socket. This makes it possible to use the conventional vehicle-side coupler assuming that the electrodes and terminals are present at the correct positions in both the socket and the connector housing, and at the same time, insert molding the L terminal when forming the L-shaped lamp socket This eliminates the need for a complicated process such as that described above, and is extremely effective in reducing the cost of this type of L-shaped lamp socket. Also, at this time, by making the connector housing and the connector terminal part a general-purpose shape,
The conventional wiring on the vehicle body side is good, and the practicality is improved.
